I am replacing all of my hoses and found that the lower radiator hose outlet is VERY close to the oil filter. The old hose was one of those flex, corrugated wire reinforced hoses. There was a section that was against the oil filter that was worn down to the wire from rubbing. I found a formed hose that matched the old hose very close (had to cut it) but without the wire it just closes off at the bend next to the filter. Seems I have 2 options........have the lower neck on the radiator moved or turned up or try a smaller oil filter. It currently has a Fram PH-11. I may try and find one of the hoses like it had before but it worries me that the one that was in there was real close to failing...... Not sure if it is the stock radiator? I am pretty sure that the Jeep originally had an F-head in it.
